A cause des constructeurs photos incapables de s'entendre sur un format RAW, préférant conserver leur format au détriment des utilisateurs, il n'est pas possible d'avoir les miniatures des images raw dans l'explorateur windows.

Petite explication sur le format RAW

Pourquoi cette multitude de formats n'est pas favorable aux utilisateurs que nous sommes, sur le site formats-ouverts.org

I used to play with cacti, and creating my own scripts, data input methods, data sources, graphs items and then graphs, but was as long way to obtain a single graph.

A smarter way is to use "SNMP - Generic OID Template" that appeared in cacti. Let's see an example : I want to graph the number of spams I've received during the last 24 hours. Counting is easy, I've just to find all files more recent than 24 hours in my IMAP folder "spam" (spamassassin does very good job !). But I had to face security considerations, because apache user had to access my maildir !

It's much simpler to expose this number via snmp, and then to create a simple graph based on Cacti "Generic OID" template. Note that SNMP is only accessible from my LAN, and the number of spams I've received is not very sensitive date. So let's go:

• Create the script /usr/local/bin/countspam.sh

#!/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
find /home/cyril/Maildir/.SPAM/cur/ -ctime -1 | wc -l

• Configure snmpd.conf to run this script and return the result

# Extensible sections.
exec .1.3.6.1.4.1.15555.1 countspam.sh /usr/local/bin/countspam.sh

• Test your query. Note that the interesting value is .1.3.6.1.4.1.15555.101.1

root:/etc # snmpwalk -c public -v2c localhost .1.3.6.1.4.1.15555.1
SNMPv2-SMI::enterprises.15555.1.1.1 = INTEGER: 1
SNMPv2-SMI::enterprises.15555.1.2.1 = STRING: "countspam.sh"
SNMPv2-SMI::enterprises.15555.1.3.1 = STRING: "/usr/local/bin/countspam.sh"
SNMPv2-SMI::enterprises.15555.1.100.1 = INTEGER: 0
SNMPv2-SMI::enterprises.15555.1.101.1 = STRING: "40"
SNMPv2-SMI::enterprises.15555.1.102.1 = INTEGER: 0
SNMPv2-SMI::enterprises.15555.1.103.1 = ""

• Connect to cacti console, click "New graph", select your host and "SNMP - Generic OID Template"
• Enter the title, OID .1.3.6.1.4.1.15555.101.1 and choose a (fun) color
• Your graph is now ready :

I have a Asus M2N-MX motherboard, with an single SATA disk, and grub correctly configured:

/boot/grub/device.map (hd0) /dev/sda

When I tried adding an IDE disk, grub refused to boot with "error 15", which means "file not found".

Obviously, grub was detecting disks in a wrong order, and was trying to load stage 1.5 from the IDE disk. To be clear, since the boot disk defined in the BIOS was the SATA, it had to be presented to grub as the first disk. So it's a buggy BIOS.

This seems to be a common behavior when mixing IDE and SATA disks. I googled about this error, but founded nothing really helpful. Changing boot order or activating onboard RAID didn't solve this error.

Then I upgraded from bios 0701 to 0903, and the problem was gone.

TIP: To upgrade Asus motherboard bios on a linux-only computer, you don't need to create a DOS bootable floppy. Recent Asus motherboard include a feature called "EZ-Flash", which is an BIOS upgrade utility included ... in the BIOS.

• Download BIOS update from Asus Website
• Unzip it and extract the .ROM file (for me M2NX0907.ROM)
• Rename this file with the motherboard model name (for me M2N-MX.ROM)
• Install mtools on your distro
• Insert a blank floppy
• Format the floppy mformat a:
• Copy the rom on the floppy mcopy M2N-MX.ROM a:
• Reboot
• During POST, press Alt-F2 to launch EZ-Update
• The BIOS upgrade procedure will start
